This is a 2-pin, through-hole PH series JST male connector and wired female connector. The pins are spaced by 2mm.

We really like the solid locking feeling and high current rating on these small connectors. This connector will mate with most of the LiPo batteries. Male and Female Connector comes as a set in the same pack. 26AWG Wire is used with female part of the connector, the whole length of the connector with wire comes as 100mm. The Male connector is PCB soldered.
